DETAILED DESCRIPTION

Implementations of the present disclosure are generally directed to mobile device applications for enabling video editing to be performed on suitable mobile processing devices. Such mobile device applications can provide an object based environment where distinct digital media units (e.g., still images, video clips, audio clips, etc.) can be imported and edited. These mobile device applications can also be operable to merge the imported digital media units based on modifications achieved in the editing environment.

FIGS. 1A and 1B illustrate an example mobile processing device 100. In the depicted example, the mobile processing device 100 is provided as a smartphone. It is appreciated, however, implementations of the present disclosure can be realized using tablet computing devices, laptop computers, personal digital assistants (PDAs), mobile phones, or any one of many other known types of suitable mobile processing devices. As shown, the mobile processing device 100 includes one or more processors 102, memory 104 (e.g., computer readable media, read-only memory (ROM), random access memory (RAM), flash memory, a removable memory card (e.g., SD card), a hard disk, or any combination thereof), a transmitter 106, a receiver 108, a keypad 110 (e.g., a soft key), a display 112, a user-interface (UI) module 114 (e.g., a graphical user interface module for touchscreen devices), speakers 116, a microphone 118, sensors 120, and a battery 122. In some examples, the processor 102 can control each component of the mobile processing device 100 and can access memory 104 to run applications 124, and/or retrieve user data 126, which can be stored in the memory. The transmitter 106 and the receiver 108 transmit and receive signals (e.g., via one or more antennas) to other communication devices, base stations, computers, satellites (e.g., GPS satellites), and/or wireless access points. The keypad 110, the display 112, the speaker 116, and the microphone 118 are input/output devices for communicating with a user. The battery 120 provides power to appropriate components of the mobile processing device.

In some examples, the processor 102 can include a display manager 128 and an input manager 130. The display manager 128 can be operable to manage displayed on the display 112. In some implementations, an operating system running on the mobile device 102 can use the display manager 128 to arbitrate access to the display 112 for a number of applications 124 running on the mobile processing device 100. In some examples, a number of applications 124 can run concurrently on the mobile processing device 100, with each application being shown to the user in respective windows on the display 112. In such examples, the display manager 128 can control which portions of each application 124 are shown on the display 112. In some implementations, the display manager 128 can control the orientation (i.e., portrait orientation or landscape orientation) of the display 112. In some examples, the input manager 130 can be operable control the handling of data received from a user via one or more input devices of the mobile processing device 100. For example, the input manager 130 can determine which application 124 should be invoked as a result of user received input. In some implementations, the UI module 114 can coordinate with the input devices to a interpret user input. The interpreted input can be evaluated by the input manager 130 to determine which application 124 should be invoked.

FIG. 2 depicts an example process 200 for editing digital media that can be performed by one or more mobile device applications executed on the mobile processing device 100. As shown, the process 200 includes obtaining a plurality of digital media units, at operation 202. Digital media units can be obtained by any one of several suitable procedures. In some examples, a digital media unit can include a digital video file, a digital image file and/or a digital audio file. In some implementations, digital media units can be obtained by accessing the user data 126 stored in memory 104. That is, digital video files, digital image files and/or a digital audio files can be stored in memory 104. In some examples, the mobile device application can enable a user to utilize the input components to select one or more digital media units stored in memory 104. In some examples, the mobile device application can copy the selected digital media units and store them in a suitable directory, or simply reference their location in memory 104. In some implementations, digital media units can also be obtained through a communications link (e.g., a wired or wireless communications link). For example, the mobile device application can enable a user to utilize the input components of mobile processing device 100 to select specific media units for downloading from a remote server or a computing system (e.g., a personal computer communicatively coupled to mobile processing device 100). The downloaded digital media units can be stored in memory 104. In some examples, digital media units can be created using and stored to the mobile processing device 100. For example, a digital camera can be used to capture digital images and/or digital video and store them as digital files on the mobile processing device 100. As another example, a microphone of the mobile processing device 100 can capture audio and store it in a digital audio file.

As shown, the process 200 also includes providing an editing environment, at operation 204. In some examples, the editing environment is an object based editing environment. In such examples, obtained digital media units can be represented as discrete objects arranged in the editing environment. In some implementations, a number of the discrete objects are arranged linearly by the mobile device application in a prescribed or random order. In some implementations, the mobile device application can enable users to rearrange the objects within the editing environment by utilizing the input components of the mobile processing device 100. In some examples, the digital media units can be arranged linearly, end-to-end, or in an overlapping manner by users. The mobile device application can also enable users to introduce additional objects to the editing environment. For example, objects representing additional digital media units can be introduced. In some implementations, objects in the editing environment can represent elements other than digital media units. For example, objects can represent effects or actions (such as transitions) to be implemented. Such objects can be imported manually by users, or automatically by the mobile device application.

As shown, the process 200 further includes merging the obtained plurality of digital media units to form a substantially continuous digital media unit, at operation 206. For example individual video clips, audio clips, and/or or still images can be merged (merged still images may be provided in the form of a slide show where each image is displayed for a predetermined duration). In some implementations, the plurality of digital media units are stitched together piece-by-piece according to the arranged configuration of representative objects in the editing environment. Further, in some examples, where an object in the editing environment represents a transition effect, the resulting “merge” of the pre-input media and the post-input media for that transition can be created based on the type of transition selected. The amount of overlap can be defined by the duration property for that transition object.

FIGS. 3A-3F depict the mobile processing device 100 running an example mobile device application (e.g., an application 124 stored in memory 104). As shown (for example in FIGS. 3A-3C), the mobile device application presents an editing environment 302 to users via the display 112 of the mobile processing device 100. A number of discrete virtual objects 304 (e.g., 304 a and 304 b) are disposed in a linear configuration within the editing environment 302. In this example, the objects 304 represent distinct digital media units available from memory 104 of the mobile processing device 100. In some implementations, the objects 304 are movable within editing environment 302. Therefore, as described above, the objects 304 can be rearranged in any prescribed order by a user. For example, a “drag-and-drop” technique can be executed by a user to rearrange the objects 304.

As shown, the mobile device application can provide a menu bar 306 including a number of selectable menu items. For example, selecting menu item 308 (“Projects”) enables a user to access previously saved projects (i.e., instances of editing environment 302), or to create new projects. Various projects can include representations of the same, or different, digital media units. Selecting menu item 310 enables the user to adjust any one of several default settings for the project (e.g., screen orientation, video or sound quality, etc.). Selecting menu item 312 enables the user to view a help file. The help file can include various resources such as troubleshooting techniques, software patch or version notes, etc. Selecting menu item 314 (“Preview”) enables the user to observe a preliminary version, or preview of a merged digital media unit (as described in greater detail below). In this example, the menu bar 306 also includes selectable toggle items 316 a (“Video”) and 316 b (“Audio”) for defining the type of digital media units that are displayed for editing.

In some implementations, the mobile device application can also provide an overview bar 318. As shown, the overview bar 318 includes a number of respective selectable tiles 320 corresponding to each object 304 in the editing environment 302. In some examples, selecting any one of tiles 320 simultaneously selects the corresponding object 304 for detailed display in the editing environment 302.

In some examples, users can add representations of additional digital media units (or other content) to the editing environment 302. Users can also modify digital media units that are already represented in the editing environment 302. For example, and with reference to FIG. 3B, when an existing object (e.g., object 304 a) is selected and displayed, various selectable editing icons are displayed within the editing environment 302. In the depicted embodiment, the editing icons include an insert icon 322 a, an insert icon 322 b and an editing icon 324. Selecting either of insertion icons 322 a, 322 b enables the user to insert a digital media unit into editing environment 302 before or after the displayed object, respectively. In some examples, a menu is displayed in response to user selection of an insertion icon 322 a, 322 b, which menu includes object, transition and title options. The user can select object from the menu to insert select a digital media object for insertion. The user can select transition from the menu to select a transition for insertion. The user can select title from the menu to input a title for insertion.

Selecting editing item 324 enables the user to modify the digital media unit represented by the selected object. In some implementations, selecting editing item 324 allows the user to access one or more contextual editing options. For example, when a selected object is representative of a video clip, the mobile device application enables users to: add and/or remove frames, adjust a default playback speed, pan and/or zoom (e.g., via the Ken Burns effect or traditional cropping), etc. Similarly, when the selected object is representative of a still image, the mobile device application enables the user to: pan and/or zoom (e.g., via the Ken Burns effect or traditional cropping), add filters, etc.

FIG. 3C shows a place holder for an additional object 326 to be imported into editing environment 302 and inserted between objects 304 a and 304 b. For example, the depiction of FIG. 3C is provided in response to user selection of the insert icon 322 b of FIG. 3B, and making a selection from the displayed menu. In the depicted example, the object 326 can be representative of a transition effect to be inserted between the digital media units represented by the objects 304 a and 304 b. As noted above, the object 326 can be inserted manually by a user utilizing editing items 322 a, 322 b. In some examples, insertion of an object can be achieved automatically by the mobile device application. As shown, when the object 326 is selected, various selectable editing icons 322 a, 322 b, 324 are displayed within editing environment 302. Selecting either of editing items 322 a, 322 b enables the user to import additional content (e.g., additional representative objects) into editing environment 302.

Selecting editing icon 324 enables the user to modify a default transition effect represented by object 326. FIG. 3D shows a menu of selectable items 332 for indicating a desired type of transition effect (e.g., “Default”, “Crossfade”, “Slide Left”, “Fall”, “Grow”, “Shrink”, etc.). The transition effect provides a visual transition between objects when the video is played. In some implementations, the transitions represented by selectable items 332 are organized in a library stored in memory 104 of mobile processing device 100. In some examples, additional transitions can be added to the library (for example, additional transitions can be downloaded from a remote server or a computing system) and represented in the menu by additional selectable items.

As described above, selectable toggle items 316 a (“Video”) and 316 b (“Audio”) can define the type of digital media units that are displayed for editing. FIG. 3E shows editing environment 302 when item 316 b is selected. In the depicted example, audio slots 328 a, 328 b are provided and recording slot 330 is provided. The audio slots 328 a, 328 b can each be populated with an audio object. In the depicted example, the audio slots 328 a, 328 b are populated by audio objects represented by audio representations 338 a, 338 b, respectively, and the recording slot 330 is empty. In this example, audio representations 338 a, 338 b are provided in the form of linear segments aligned with a video timeline 340 (e.g., a frame-by-frame timeline). In some implementations, however, audio representations can be provided in the form of discrete objects that are movable within editing environment 302. In some example, when an audio slot is empty, an insert icon is displayed. In response to user selection of the insert icon, an audio object selection menu can be displayed, which the user can navigate to select an audio object for populating the audio slot.

Audio editing icons 334 a, 334 b, 336 are displayed. The audio editing icons 334 a, 334 b, 336 and audio representations 338 a, 338 b overlay frames of the objects that make up the video. Selecting either of editing icons 334 a, 334 b enables the user to edit an audio track represented by the audio representation 338 a, 338 b, respectively. In some examples, audio editing options include accelerating or decelerating the audio playback speed and/or setting start and end time points for the respective audio object relative to a timeline of the underlying video. Selecting icon 336 enables the user to record an audio file and import a representation of the recorded file into editing environment 302.

As described above, selecting the appropriate menu item enables the user to observe a preliminary version of the merged digital media unit. The merged digital media unit can include a combination of the digital media units and effects embodied by the representations imported into editing environment 302. In some implantations, a number of the digital media units and effects are combined in a chronological order prescribed by the arrangement of discrete objects in editing environment 302. FIG. 3F shows a preview screen presented to users via display 112 of mobile processing device 100. As shown, the preview screen includes a selectable media item 342. Selecting the media item can allow users to observe the merged digital media unit. Additionally, in this example, menu bar 306 includes selectable menu item 344 (“Export”), in addition to the various other menu items described above. Selecting menu item 344 can allow users to export the merged digital media unit to a specified location in memory 104 of mobile processing device 100.

Implementations of the present disclosure can also be realized as one or more computer program products, i.e., one or more modules of computer program instructions encoded on a computer readable medium for execution by, or to control the operation of, data processing apparatus. The computer readable medium can be a machine-readable storage device, a machine-readable storage substrate, a memory device, a composition of matter effecting a machine-readable propagated signal, or a combination of one or more of them. The term “data processing apparatus” encompasses all apparatus, devices, and machines for processing data, including by way of example a programmable processor, a computer, or multiple processors or computers. The apparatus can include, in addition to hardware, code that creates an execution environment for the computer program in question, e.g., code that constitutes processor firmware, a protocol stack, a database management system, an operating system, or a combination of one or more of them.

A computer program (also known as a program, software, software application, script, or code) can be written in any form of programming language, including compiled or interpreted languages, and it can be deployed in any form, including as a stand alone program or as a module, component, subroutine, or other unit suitable for use in a computing environment. A computer program does not necessarily correspond to a file in a file system. A program can be stored in a portion of a file that holds other programs or data (e.g., one or more scripts stored in a markup language document), in a single file dedicated to the program in question, or in multiple coordinated files (e.g., files that store one or more modules, sub programs, or portions of code). A computer program can be deployed to be executed on one computer or on multiple computers that are located at one site or distributed across multiple sites and interconnected by a communication network.

The processes and logic flows described in this disclosure can be performed by one or more programmable processors executing one or more computer programs to perform functions by operating on input data and generating output. The processes and logic flows can also be performed by, and apparatus can also be implemented as, special purpose logic circuitry, e.g., an FPGA (field programmable gate array) or an ASIC (application specific integrated circuit).

Processors suitable for the execution of a computer program include, by way of example, both general and special purpose microprocessors, and any one or more processors of any kind of digital computer. Generally, a processor will receive instructions and data from a read only memory or a random access memory or both.

Similarly, while operations are depicted in the drawings in a particular order, this should not be understood as requiring that such operations be performed in the particular order shown or in sequential order, or that all illustrated operations be performed, to achieve desirable results. In certain circumstances, multitasking and parallel processing can be advantageous. Moreover, the separation of various system components in the implementations described above should not be understood as requiring such separation in all implementations, and it should be understood that the described program components and systems can generally be integrated together in a single software product or packaged into multiple software products.

Thus, particular implementations of the present disclosure have been described. Other implementations are within the scope of the following claims. For example, the actions recited in the claims can be performed in a different order and still achieve desirable results. A number of implementations have been described.
